hours (field or road operation), and then every 200 hour intervals thereafter.

Each caster is equipped with two fluid-filled anti-shimmy
dampeners (A).
Mounting bolts (B) and (C) need to be checked periodically for
security. For inspection intervals, refer to
•
Two inboard bolts (B) should be tightened to 136 Nm
(100 lbf·ft)
•
Outboard bolt (C) should be tightened to 244 Nm (182 lbf·ft)
